Title: Purifying gases - passing gas through active C bed, purging adsorbed mater-ial with gas stream, and oxidising by passing through adsorbent contg oxidation cat
IPC: B01J23/22
Filed: 1973-08-02
Abstract: Low concentrations of undesirable materials, e.g. org. solvents, excess monomers, uncombusted hydrocarbons, NO and CO, are eliminated from gases by (a) passing the gas into a bed of active carbon to adsorb the undesirable material, (b) purging the adsorbed undesirable material by passing a gas stream through the bed, and (c) passing the purge gas contg. the undesirable material into a bed of an adsorbant impregnated with an oxidn. catalyst while controlling the temp. of the bed at a value below its inflammation temp. Method gives efficient elimination of low concentrations of undesirable materials, rapid oxidn. of the undesirable material and repeated use of the bed of activated carbon.

Title: Heat pump for hot water central heating - has thermostatic valve on evaporator forming hot water by-pass controller
IPC: F24D3/18
Filed: 1974-03-06
Abstract: A heat pump for central heating, where water pumped around a series of radiators is heated by a circuit which includes a compressor and a pressure reducer through which passes a refrigerating fluid and also employing an evaporator and heat exchanger, has a temperature detector on the evaporator to control the flow of hot water when the evaporator reaches freezing temperature. This device is thermostatically operated and acts as a by pass for the radiator system, and has a flow control flap actuated by the thermostat, so that the flow through the radiators is altered without altering the pump output, and the efficiency of the heat exchanger is increased at the same time by the additional flow through it. This thermostatically operated valve also controls the speed of the circulation pump.

Title: Sheet collating machine with upright frame - has sloping shelves and crank drive to swing extractor arms for sheet selection
IPC: B65H39/042
Filed: 1975-02-07
Abstract: A machine for producing a set of sheets for compiling a catalogue, has an upright frame with a et of twelve compartments each with sloping slides (3) carrying a plate (4) on which is stached a pile of pages (2). A shaft (15) at the base is rotated by a motor , to rotate a crank arm (14) which moves a long arm (13) upwards to move two levers (10, 12) upwards in a scissor action. This causes a longer arm (7) extending from top to bottom to shift rearwards.

Title: Stabilising granular ground - using coaxial pipes oscillated in ground for spreading stabilising medium
Inventor: GILBERD GORDON HENRY
IPC: E02D3/10
Filed: 1975-10-15
Abstract: The machine used for solidifying of granular ground ensures that the ground is made suitable and stable for later construction work. The arrangement has a pair of pipes (1, 2) held coaxially with a clearance between them.

Title: Antibronchoconstricting furo benzoxazol acethydroxamic acids prepn. - by treating the corresp. ethyl ester with hydroxyl amine
Inventor: TURIN MICHEL
IPC: C07D307/79
Filed: 1976-01-16
Abstract: Furobenzoxazolacethydroxamic acids of formula (I) are new (where n and m=0 or 1 and are different; R 1-4C alkyl). A typical compound is 6-methylfuro 2,3-e benzoxazol-2-yl acethydroxamic acid. This was prepd. from 2-methoxycarbonyl-3-methyl-6-hydroxybenzofuran by nitration to give the 7-nitro deriv. redn. to the amine and treatment with ethyl acetimidate to give 2, 6-dimethyl-5-methoxycarbonyl furo 2,3-e benzoxazole. This was converted to the free acid and decarboxylated to form 2,6-dimethyl furo 2,3-e benzoxazole. Treatment with HCl then with ethyl ethoxycarbonyl acetimidate gave ethyl l-methyl furo 2,3-e benzoxazol-2-yl acetate. Finally 0.045 mole of this prod. was treated with 0.1 mole Na and 0.05 mole hyroxylamine hydrochloride to give the desired prod. m.pt. 233 degree C. Used as anti-bronchoconstrictors.

The holder is mounted on the rod by the two strips. The snap fastening assembly of these elements is not readily apparent to anyone except those authorised to handle the goods so that the risk of theft of the articles is minimised.

Title: Coal hydrogenation with extremely brief reaction times - minimising gas prodn and polymerisation of liquid components
IPC: C10G1/06
Filed: 1976-05-21
Abstract: A coal hydrogenation process comprises adding hot hydrogen to the coal in an H/C ratio of 0.05-4, reacting at 400-2000 (pref. 500-1500) degrees C and 500-5000 (pref. 600-3000) psig quenching the reaction effluent with H2 at 200 dgrees C, the total residence time being from 2 millisecs. to 2 secs.
